1 Claim.

The object of this invention is to provide a new and improved form of gas and coal range in which the range is provided with seven gas burners, four of which are open burners on the top of the range and three of the burners are oven burners.

Another object of the invention is to make the range so that the six handles that control all seven burners are arranged in a single panel in one straight line on the front of the range.

Another object of the invention is put the two halves for the three oven burners on the back of the range and connect these valves to the handles that move them by long rods.

Another object of the invention is to pipe the gas from the control valve to the mixing valves on the ovens by pipes which are placed on the back of the range.

This and other objects of the invention will be illustrated in the drawings, described in the specification and pointed out in the claim at the end thereof.

In the drawings:

Figure 1 is a diagrammatic view of the arrangement of the six control valves and the handles by which they are operated.

Figure 2 is a vertical section through the handle at the bottom of Figure l, and at the right of Figure 4.

Figure 3 is a top plan view of the right hand side of the range, the range being partly broken away.

Figure 4 is an enlarged detail view of a portion of a panel at the front of the range with the handles mounted thereon.

Figure 5 is a side elevation of the parts shown in Figure 3, the view being taken at the right hand side of the range.

Figure 6 is an elevation of the upper part of the back of the range, the coal portion of the range being omitted.

Figure 7 is an elevation of the three way valve.

Figure 8 is a vertical section on the line 8a:8a: in Figure 7.

Figure 9 is a perspective view of the front of the range.

-In the drawings, like reference numerals indicate like parts.

In the drawings reference numeral l indicates the panel or keyboard of the gas portion of the range, on which are mounted a series of handles 2, 3, 4, 5, 6 and 1. The handles 2, 3, 4, and 5, control valves 8, 9, l0 and II, which control the flow of gas to the gas burners l2, l3, l4 and I5. These gas burners are arranged in the ordinary arrangement on gas ranges. The handles 6 and 1 are connected by the long rods l6 and I! to the valves I8 and I9. This is a part of our invention. The connection between the rods and the valve stems is made by sleeves 20 and 2|, which are fastened thereto by set screws 23, 23. It will also be understood that the rod l6 extends back inside of the housing 24 and the rod ll extends back outside of the housing. 7

The supply of gas is fed through the pipe 25, which feeds it to the valves l8 and I9 at the back of the range and also feeds the gas to the valves 8, 9, I9, and H at the front of the range. The gas passes from the valve l8 to the pipe 21', to the connections 28, to a temperature regulator 29 on the side of the range, and then down through the pipe 30 to the mixing pipe 3 I, from which it passes to the burner in one of the ovens.

The gas also passes through the three way valve 19 into either of the pipes 35 or 36 to the mixing valve 31 or 38 and from there into burners, not shown, at the top or bottom of the oven, so that the oven can be heated at the top or bottom and can be used for either broiling or baking. The three way valve is shown in section in Figure 8 and the three way openings are shown in dotted lines in Figure 7, the outlets being indicated at 39, 40 and 4|.

As shown in Figure 7 the gas is shut off. If the valve is given a quarter turn to the right from the zero position, the gas flows up through the pipe 35. If the valve is given a quarter turn to the left from the zero position, the gas will flow up through the pipe 36.

This three way valve I9 is controlled by the handle I. This handle 1 is provided with a safety device which consists of a locking pin 59 which engages with an opening 5| in the panel. This locking pin holdsthe handle 1 in the zero position with the valve l9 closed. The pin 59 is held in engagement with the panel opening 5| by a helical spring 52 which surrounds the reduced portion of the pin. The pin makes threaded engagement with the handle 54, by which the pin can be drawn out of engagement with the panel opening so that the handle I can be turned a quarter turn either to the right or the left.

To limit the movement of the valve to degrees, on the rear end of the valve I provide as follows. The valve housing is cut away in a semicircular depression 56 on which travels a lug 51 which is carried on and moves with the valve. This lug is limited in its movement by the stops 58 and 59. This lug is normally held in the zero position shown in Figure '7 by the engagement of the pin 50 with the opening 5|. When the pin ately behind said panel and extending to the rear of the stove for connection-to a gas main, valves connected to said gas supply pipe for some of said handles and concealed by said panel, burners on the top of the gas range substantially on a level with said control panel connected to and controlled by said valves, an oven located higher up on the range than said burners with an open space between them, a back panel located at the rear of the top of the range behind said burners and extending up to the rear of the underside of said oven, a burner in said oven, a valve on a level with said control panel and connected to the main gas supply pipe at the back of the range, a rod connecting said valve directly to a handle on said panel, all of said handles and valves having horizontal axes, a gas supply pipe back of the back panel of the range leading updirectly from said valve to the burner in the oven higher up, said ,oven gas supply pipe and said valve being concealed from view from in front of the range by "said back panel and being short and direct.
